2014 Reporting of Sexual Assault: Institutional Comparisons

Institutions of higher education are required to submit annual reports of sexual assault crimes to the Department of Education under the Clery Act. The Department of Education makes this data publicly available. Two primary measures are used to assess reporting of assault on campus: the Assault Reporting Ratio (ARR) and the Reporting Rate per 10,000 students (R10K). These measures are easily calculated and can be used to assess practices and policies that impact the reporting of sexual assault on campus. The ARR and R10K are rate comparisons, a method widely used in public health. These rate comparisons measure how close the institution is to reporting the anticipated number of assaults occurring on campus. Use of these measures allows comparisons between institutions and between years in the same institution. They serve as benchmarks to identify best practices and the impact of legal changes. The Assault Reporting Ratio compares the reported number of assaults to an estimate of the expected number of assaults. The expected estimate is based on gender-specific assault rates, and college-level (undergraduate or graduate) enrollment based on anonymous survey data. The ARR is expressed as a percentage. An ARR of 100% indicates that the school is counting all of the assaults predicted by national surveys. The R10K is the reported number of assaults per 10,000 students, calculated from the data provided by the institution. During 2014, 10,607,238 students were enrolled at 1,332 institutions, 82% undergraduates and 18% graduates. A total of 6,429 sexual assaults were reported for all institutions combined. A quarter of institutions (25.7% or 343 colleges) reported no sexual assaults. The summary statistics include all schools with zero reports. Overall, in 2014, there were 6 reports of sexual assault per 10,000 students (R10K measure). At individual colleges, the range of assault reports was from zero to 215 reports per 10,000 students with a median of 4 (10 IQR). The mean R10K was 9.5 (16.9 SD). The expected number of assaults in the same population was 282,399. The overall ARR for the country is the reported assaults (6,429) divided by the expected number of assaults (282,399). This figure, 2.3%, indicates that 97.7% of the expected assaults are not reported to the colleges. The median ARR was 1.6% and the mean ARR was 3.5%. The standardized measures can be used to evaluate institutional policies, changes in programs, and procedures for reports.

Performance Characterization of a Solenoid-type Gas Valve for the H−H^{-} Magnetron Source at FNAL

The magnetron-style $H^{-}$ ion sources currently in operation at Fermilab use piezoelectric gas valves to function. This kind of gas valve is sensitive to small changes in ambient temperature, which affect the stability and performance of the ion source. This motivates the need to find an alternative way of feeding H2 gas into the source. A solenoid-type gas valve has been characterized in a dedicated off-line test stand to assess the feasibility of its use in the operational ion sources. $H^{-}$ ion beams have been extracted at 35 keV using this valve. In this study, the performance of the solenoid gas valve has been characterized measuring the beam current output of the magnetron source with respect to the voltage and pulse width of the signal applied to the gas valve.Comment: 4 pp. arXiv admin note: text overlap with arXiv:1701.0175

Nuclear electric propulsion operational reliability and crew safety study: NEP systems/modeling report

The objective of this study was to establish the initial quantitative reliability bounds for nuclear electric propulsion systems in a manned Mars mission required to ensure crew safety and mission success. Finding the reliability bounds involves balancing top-down (mission driven) requirements and bottom-up (technology driven) capabilities. In seeking this balance we hope to accomplish the following: (1) provide design insights into the achievability of the baseline design in terms of reliability requirements, given the existing technology base; (2) suggest alternative design approaches which might enhance reliability and crew safety; and (3) indicate what technology areas require significant research and development to achieve the reliability objectives

Judge Agreement and Student Rotation: A Real-Life Study of the 1990 DSR-TKA National Forensics Tournament

During the third round of Poetry competition at the 1990 DSR-TKA National Tournament, a student approached the Tab Room and asked why the same people were competing against each other in the first and third rounds. After examining the schematics, it was determined that, indeed, the first and third rounds were identical. At that point in the tournament schedule, it was impossible to reschedule or redo the schematic, so the tournament continued as originally scheduled. Instead of treating this as a crisis, it became an excellent real-life opportunity for research. Thus, this study examines the ranks between Rounds One and Two, Two and Three, and Three and One to see what we can learn about judge agreement and student rotation/scheduling
